Secondo, a travel case worthy of the name is given and that I highly appreciate: I pass all my weekend away from Paris. (There are two brushes but only one case ... Do not exaggerate either :-)
Finally, I would add, but it's personal, the color (deep black) to me is far more pleasant than the candy pink and blue skies I've seen until now ... It gives the impression of be a brush .. adult.
As always with Oral B, the battery is a marvel: at 2 minutes per brushing, a full charge gives you several weeks of use without worry. Better: a witness warns that the load decreases WIDELY BEFORE it is too late. I could use this brush several days despite the (I had forgotten to charge it before leaving on weekends). Well seen!
There is only one base, but it should not be a problem since you will not have to charge it once a month or so.
Side brush, we feel that there is work. We did not put 3 to 4 tufts of red hair here, a pinch of blue and green hairs here and there, and a little white around like that, blindly. This is contrary to the well studied and different combinations are available to suit each case: sensitive gums, tooth whitening, etc. The site of Oral B offers 11 different brushes. You should find your account (note that the site of Oral B reference here - Amazon - for shopping online.
You can also purchase unbranded brush (available also on Amazon). They are very well (I ordered a dozen), although we feel that this is not of the same quality. They are soft, which is a very good thing, but tend to deteriorate faster. Make some tests for you to realize.
And feel free to ask me questions about this, I'd be happy to answer :)
